20SC w/ 115 #'s and opinions needed

[mrobertson]

Today i splashed my 1989 Tracker 20 with a brand new 2005 Yamaha 115 V-4 2 stroke. I bought the engine leftover, still in the crate, so its brand new not rebuilt.

My restoration pics are in the repairs section. Boat has a new deck, new 50 gallon fuel tank, no T-Top, and a 25 inch transom. It's a very basic fly fishing and light tackle setup, so it's probably pretty light compared to others.


Bare in mind, i have 3 hours on the engine. After i got through the first hour of break in, i could push to WOT and trim it back to 4000 RPM's.

4000 RPM's - 25 mph
4200 RPM's - 27 mph
4600 RPM's - 30 mph

I don't have alot of time yet opening it up but the few times i have i only get to 5000 - 5100 RPM's and about 31 - 32 mph.

I almost feel like the prop loses it's "bite" if that makes sense. Running 30 mph, i have plenty left on the throttle but the boat doesn't go anywhere when i open it up.

The prop i am running is a 13.25 x 17p ALUMINUM prop. I'm 100% certain i could do better with a different prop.

So - i'm rolling over to you, prop gods.................what kind of prop should i look for?!?!?!
